反吊桥主缆索张拉过程分析

以拟定的某反吊桥方案为对象 ,对张拉主缆索调整主梁应力过程及张拉主缆索过程中全桥的整体稳定性作了计算分析。结果表明 ,张拉主缆索可以显著地改善反吊桥主梁的应力。

Analysis of Tensioned Process of Main Cable of Reverse Suspension Bridge

It makes the calculation analysis of the integral stability of the whole bridge in the process of tensioned main cable and adjustment main beam stress and the process of tensioned main cable taking the proposed reverse suspension bridge as the object. The result shows that to tension the main cable can obviously improve the stress of the main girder of the reverse suspension bridge.
